BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to methods and catalysts for generating a hydrogen-rich gas from gas mixtures containing carbon monoxide and water, such as water-containing syngas mixtures. More particularly, the invention includes methods using platinum-free catalysts which contain ruthenium and cobalt, and ruthenium, cobalt and molybdenum. The catalysts may be supported on a variety of catalyst support materials. The ruthenium-cobalt catalysts of the invention exhibit both high activity and selectivity to hydrogen generation and carbon monoxide oxidation.

2. Discussion of the Related Art

Numerous chemical and energy-producing processes require a hydrogen-rich composition (e.g. feed stream.) A hydrogen-rich feed stream is typically combined with other reactants to carry out various processes. Nitrogen fixation processes, for example, produce ammonia by reacting feed streams containing hydrogen and nitrogen under high pressures and temperatures in the presence of a catalyst. Fuel cells such as polymer electrode membrane (“PEM”) fuel cells, produce energy from a hydrogen-rich feed stream. PEM fuel cells typically operate with a feedstream gas inlet temperature of less than 450° C. Carbon monoxide is excluded from the feed stream to the extent possible to prevent poisoning of the electrode catalyst, which is typically a platinum-containing catalyst. See U. S. Pat. No. 6,299,995.

One route for producing a hydrogen-rich gas is hydrocarbon steam reforming. In a hydrocarbon steam reforming process steam is reacted with a hydrocarbon fuel, such as methane, iso-octane, toluene, etc., to produce hydrogen gas and carbon dioxide. The reaction, shown below with methane (CH₄), is strongly endothermic: CH₄+2H₂O→4H₂+CO₂ In the petrochemical industry, hydrocarbon steam reforming of natural gas is typically performed at temperatures in excess of 900° C. Even for catalyst assisted hydrocarbon steam reforming the temperature requirement is often still above 700° C. See, for example, U.S. Pat. No. 6,303,098. Steam reforming of hydrocarbons such as methane, using nickel- and gold-containing catalysts and temperatures greater than 450° C., is described in U.S. Pat. No. 5,997,835. The catalyzed process forms a hydrogen-rich gas, with depressed carbon formation.

One example of effective hydrocarbon steam reforming catalysts is the Sinfelt compositions which are composed of Pt, a Group 11 metal, and a Group 8 to 10 metal. Group 11 metals include Cu, Ag and Au while Group 8 to 10 metals include the other noble metals. These catalyst formulations are well known in the promotion of hydrogenation, hydrogenolysis, hydrocracking, dealkylation of aromatics, and naphtha reforming processes. See, for example, U.S. Pat. Nos. 3,567,625 and 3,953,368. The application of catalysts based on the Sinfelt model to the water gas shift (“WGS”) reaction, in particular at conditions suitable for lower temperature WGS applications such as PEM fuel cells, has not been previously reported.

Purified hydrogen-containing feed streams have also been produced by filtering the gas mixture produced by hydrocarbon steam reformation through hydrogen-permeable and hydrogen-selective membranes. See, for example, U.S. Pat. No. 6,221,117. Such approaches suffer from drawbacks due to the complexity of the system and slow flow rates through the membranes.

Another method of producing a hydrogen-rich gas such as a feed stream starts with a gas mixture containing hydrogen and carbon monoxide with the absence of any substantial amount of water. The carbon monoxide can be removed by absorption and/or by its oxidation to carbon dioxide. Such a process utilizing a ruthenium based catalyst to remove and oxidize the carbon monoxide is disclosed in U.S. Pat. No. 6,190,430.

The WGS reaction provides another mechanism for producing a hydrogen-rich gas but from water (steam) and carbon monoxide. An equilibrium process, the water gas shift reaction, shown below, converts water and carbon monoxide to hydrogen and carbon dioxide, and vice versa. H₂O+CO

H₂+CO₂ Various catalysts have been developed to catalyze the WGS reaction. These catalysts are typically intended for use at temperatures greater than 450° C. and/or pressures above 1 bar. For instance, U.S. Pat. No. 5,030,440 relates to a palladium and platinum-containing catalyst formulation for catalyzing the shift reaction at 550 to 650° C. See also U.S. Pat. No. 5,830,425 for an iron/copper based catalyst formulation.

Catalytic conversion of water and carbon monoxide under water gas shift reaction conditions has historically been used to produce hydrogen-rich and carbon monoxide-poor gas mixtures. Existing WGS catalysts, however, do not exhibit sufficient activity at a given temperature to reach or even closely approach thermodynamic equilibrium concentrations of hydrogen and carbon monoxide such that the product gas may subsequently be used as a hydrogen feed stream. Specifically, existing catalyst formulations are not sufficiently active at low temperatures, i.e. temperatures below about 450° C. See U.S. Pat. No. 5,030,440.

Platinum (Pt) is a well-known catalyst for both hydrocarbon steam reforming and water gas shift reactions. Under the typical hydrocarbon steam reforming conditions of high temperature (above 850° C.) and high pressure (greater than 10 bar), the WGS reaction may occur post-reforming over the hydrocarbon steam reforming catalyst due to the high temperature and generally unselective catalyst compositions. See, for instance, U.S. Pat. Nos. 6,254,807; 5,368,835; 5,134,109 and 5,030,440 for a variety of catalyst compositions and reaction conditions under which the water gas shift reaction may occur post-reforming. A drawback to the use of Pt in catalyst compositions is its expense.

Metals such as cobalt (Co), ruthenium (Ru), palladium (Pd), rhodium (Rh) and nickel (Ni) have also been used as WGS catalysts but are normally too active for the selective WGS reaction and cause methanation of CO to CH₄ under typical reaction conditions. In other words, the hydrogen produced by the water gas shift reaction combines with CO in the presence of WGS catalysts to yield methane. This tendency toward methanation has typically limited the utility of metals such as Co, Ru, Pd, Rh and Ni as water gas shift catalysts.

A need exists, therefore, for a method of producing a hydrogen-rich syngas using relatively inexpensive platinum-free catalysts which are highly active and highly selective for both hydrogen generation and carbon monoxide oxidation at moderate temperatures (i.e. below about 450° C.) to provide a hydrogen-rich gas, such as a hydrogen-rich syngas, from a gas mixture containing, at least CO, and preferably hydrogen.

In a third general embodiment, the invention is directed to the aforementioned water gas shift catalysts of the second general embodiment in an apparatus for generating a hydrogen gas containing stream from a hydrocarbon or substituted hydrocarbon feed stream. The apparatus further comprises, in addition to the WGS catalyst, a fuel reformer, a water gas shift reactor and a temperature controller.

DETAILED DESCRIPTION OF THE INVENTION

The invention relates to a method for producing a hydrogen-rich gas, such as a hydrogen-rich syngas. According to the method a CO-containing gas, such as a syngas, contacts a water gas shift catalyst in the presence of water, preferably a stoichiometric excess of water and preferably at a reaction temperature of less than about 450° C., to produce a hydrogen-rich gas, such as a hydrogen-rich syngas. The reaction pressure is preferably not more than about 10 bar. The invention also relates to a water gas shift catalyst itself and to apparatus such as water gas shift reactors and fuel processing apparatus comprising such WGS catalysts.

A water gas shift catalyst with an essential absence of Pt according to the invention comprises:

-   -   (a) Ru, its oxides or mixtures thereof;     -   (b) Co, Mo, their oxides or mixtures thereof; and     -   (c) at least one of Li, Na, K, Rb, Cs, Ti, Zr, Cr, Fe, La, Ce,         Eu, their oxides and mixtures thereof. The WGS catalyst may be         supported on a carrier, such as any one member or a combination         of alumina, zirconia, titania, ceria, magnesia, lanthania,         niobia, zeolite, perovskite, silica clay, yttria and iron oxide.

The WGS catalysts of the invention comprise combinations of at least three metals or metalloids, selected from Ru, Co, Mo, and group c) as indicated above, in each and every possible permutation and combination, except as specifically and expressly excluded.

Discussion regarding the particular function of various components of catalysts and catalyst systems is provided herein solely to explain the advantage of the invention, and is not limiting as to the scope of the invention or the intended use, function, or mechanism of the various components and/or compositions disclosed and claimed. As such, any discussion of component and/or compositional function is made, without being bound by theory and by current understanding, unless and except such requirements are expressly recited in the claims. Generally, for example, and without being bound by theory, ruthenium metal has activity as a WGS catalyst. Co, Mo and the group of metals comprised of Li, Na, K, Rb, Cs, Ti, Zr, Cr, Fe, La, Ce and Eu may themselves have activity as WGS catalysts but function in combination with Ru to impart beneficial properties to the catalyst of the invention.

Catalysts of the invention can catalyze the WGS reaction at varying temperatures, avoid or attenuate unwanted side reactions such as methanation reactions, as well as generate a hydrogen-rich gas, such as a hydrogen-rich syngas. The composition of the platinum-free WGS catalysts of the invention and their use in WGS reactions are discussed below.

1. Definitions

Water gas shift (WGCS) reaction: Reaction which produces hydrogen and carbon dioxide from water and carbon monoxide, and vice versa: H₂O+CO

H₂+CO₂

Generally, and unless explicitly stated to the contrary, each of the WGS catalysts of the invention can be advantageously applied both in connection with the forward reaction as shown above (i.e., for the production of H₂), or alternatively, in connection with the reverse reaction as shown above (i.e., for the production of CO). As such, the various catalysts disclosed herein can be used to specifically control the ratio of H₂ to CO in a gas stream.

Methanation reaction: Reaction which produces methane and water from a carbon source, such as carbon monoxide or carbon dioxide, and hydrogen: CO+3H₂→CH₄+H₂O CO₂+4H₂→CH₄+2 H₂O

“Syngas” (also called synthesis gas): Gaseous mixture comprising hydrogen (H₂) and carbon monoxide (CO) which may also contain other gas components such as carbon dioxide (CO₂), water (H₂O ), methane (CH₄) and nitrogen (N₂).

LTS: Refers to “low temperature shift” reaction conditions where the reaction temperature is less than about 250° C., preferably ranging from about 150° C. to about 250° C.

MTS: Refers to “medium temperature shift” reaction conditions where the reaction temperature ranges from about 250° C. to about 350° C.

HTS: Refers to “high temperature shift” reaction conditions where the reaction temperature is more than about 350° C. and up to about 450° C.

Hydrocarbon: Compound containing hydrogen, carbon, and, optionally, oxygen.

The Periodic Table of the Elements is based on the present IUPAC convention, thus, for example, Group 9 comprises Co, Rh and Ir. (See http://www.iupac.org dated May 30, 2002).

As discussed herein, the catalyst composition nomenclature uses a dash (i.e., “−”) to separate catalyst component groups where a catalyst may contain one or more of the catalyst components listed for each component group, brackets (i.e., “{ }”) are used to enclose the members of a catalyst component group, “{two of . . . }” is used if two or more members of a catalyst component group are required to be present in a catalyst composition, “blank” is used within the “{ }” to indicate the possible choice that no additional element is added, and a slash (i.e., “/”) is used to separate supported catalyst components from their support material, if any. Additionally, the elements within a catalyst composition formulation include all possible oxidation states, including oxides, or salts, or mixtures thereof.

Using this shorthand nomenclature in this specification, for example, “Pt—{Rh, Ni}—{Na, K, Fe, Os}/ZrO₂” would represent catalyst compositions containing Pt, one or more of Rh and Ni, and one or more of Na, K, Fe, and Os supported on ZrO₂; all of the catalyst elements may be in any possible oxidation state, unless explicitly indicated otherwise. “Pt—Rh—Ni—{two of Na, K, Fe, Os}” would represent a supported or unsupported catalyst composition containing Pt, Rh, and Ni, and two or more of Na, K, Fe, and Os. “Rh—{Cu,Ag,Au}—{Na, K, blank}/TiO₂” would represent catalyst compositions containing Rh, one or more of Cu, Ag and Au, and, optionally, and one of Na or K supported on TiO₂.

The description of a catalyst composition formulation as having an essential absence of an element, or being “element-free” or “substantially element free” does allow for the presence of an insignificant, non-functional amount of the specified element to be present, for example, as a non-functional impurity in a catalyst composition formulation. However, such a description excludes formulations where the specific element has been intentionally or purposefully added to the formulation to achieve a certain measurable benefit. Typically, with respect to noble metals such as Pt for example, amounts less than about 0.01 weight percentage would not usually impart a material functional benefit with respect to catalyst performance, and therefore such amounts would generally be considered as an insignificant amount, or not more than a mere impurity. In some embodiments, however, amounts up to less than about 0.04 weight percent may be included without a material functional benefit to catalyst performance. In other embodiments, amounts less than about 0.005 weight percent would be considered an insignificant amount, and therefore a non-functional impurity.

2. WGS Catalyst

A platinum-free water gas shift catalyst of the invention comprises:

-   -   (a) Ru, its oxides or mixtures thereof;     -   (b) Co, Mo, their oxides or mixtures thereof; and     -   (c) at least one of Li, Na, K, Rb, Cs, Ti, Zr, Cr, Fe, La, Ce,         Eu, their oxides and mixtures thereof. The catalyst components         are typically present in a mixture of the reduced or oxide         forms; typically one of the forms will predominate in the         mixture. The catalysts of the invention may be supported on         carriers. Suitable carriers for supported catalysts are         discussed below.

A WGS catalyst of the invention may be prepared by mixing the metals and/or metalloids in their elemental forms or as oxides or salts to form a catalyst precursor. This catalyst precursor mixture generally undergoes a calcination and/or reductive treatment, which may be in situ (within the reactor), prior to use as a WGS catalyst. Without being bound by theory, the catalytically active species are generally understood to be species which are in the reduced elemental state or in other possible higher oxidation states. The catalyst precursor species are believed to be substantially completely converted to the catalytically active species by the pre-use treatment. Nonetheless, the catalyst component species present after calcination and/or reduction may be a mixture of catalytically active species such as the reduced metal or other possible higher oxidation states and uncalcined or unreduced species depending on the efficiency of the calcination and/or reduction conditions.

A. Catalyst Compositions

As discussed above, one embodiment of the invention is a platinum-free catalyst for catalyzing the water gas shift reaction (or its reverse reaction). According to the invention, a WGS catalyst may have the following composition:

-   -   (a) Ru, its oxides or mixtures thereof;     -   (b) Co, Mo, their oxides or mixtures thereof; and     -   (c) at least one of Li, Na, K, Rb, Cs, Ti, Zr, Cr, Fe, La, Ce,         Eu, their oxides and mixtures thereof.

The amount of each component present in a given catalyst according to the present invention may vary depending on the reaction conditions under which the catalyst is intended to operate. Generally, the ruthenium component may be present in an amount ranging from about 0.01 wt. % to about 10 wt. %, preferably about 0.01 wt. % to about 2 wt. %, and more preferably about 0.05 wt. % to about 0.5 wt. %.

Cobalt may be present as either a bulk catalyst or a supported catalyst composition. Bulk cobalt catalysts may have Co concentration ranging from a high of about 90% to a low of about 30%, preferred is about 40% to about 70%; generally a bulk cobalt catalyst may contain about 10 wt. % binder. Bulk cobalt catalysts may also contain other components such as zirconium, magnesium, silicon or aluminum. Supported cobalt catalysts may have Co concentrations ranging from about 0.05% up to about 25 wt. % Co, with about 0.10% to about 15% a preferred range for Co concentration.

The lanthanide elements and transition metals may be present, typically, in amounts ranging from about 0.05 wt. % to about 20 wt. %, preferably about 0.1 wt. % to about 15 wt. %. The main group and metalloid elements may be present in amounts ranging, generally, from about 0.01 wt. % to about 15 wt. %, preferably about 0.02 wt. % to about 10 wt. %.

The above weight percentages are calculated on the total weight of the catalyst component, in its final state in the catalyst composition after the final catalyst preparation step (i. e., the resulting oxidation state or states) with respect to the total weight of all catalyst components plus the support material, if any. The presence of a given catalyst component in the support material and the extent and type of its interaction with other catalyst components may effect the amount of a component needed to achieve the desired performance effect.

In a preferred embodiment, the platinum-free water gas shift catalyst of the invention comprises Ru, Co and at least one of Zr, Ti and Eu.

In another preferred embodiment, the platinum-free water gas shift catalyst comprises Ru, Co and at least one of Cr, Mo, Fe, La and Ce. In a particularly preferred embodiment, the platinum-free water gas shift catalyst comprises Ru, Co, Fe and at least one of Cr, La and Ce. In another particularly preferred embodiment, the platinum-free catalyst comprises Ru, Co and Fe. Another particularly preferred embodiment includes Ru—Co—Fe—{Na, K}.

In yet another preferred embodiment, the platinum-free water gas shift catalyst comprises Ru and Co, at least one of Li, Na, K, Rb, Cs and Zr. Particularly preferred embodiments include Ru—Co—{Na, K, Rb} and Ru—Co—Na—Li.

In another preferred embodiment, the platinum-free water gas shift catalyst comprises Ru, Co, and Mo.

The catalysts may be more advantageously applied in specific operating temperature ranges. For instance, addition of alkali metals to the Ru—Co core significantly enhances the LTS and MTS activity of the supported or unsupported catalysts. A preferred alkali metal is Na for LTS and Na or K for MTS. Ru—Co—Na catalyst compositions maintain their high LTS and MTS activity on any support. Exemplary supports include not only zirconia, titania, bulk Co and ceria but also less expensive silicas and aluminas. One preferred embodiment is Ru and/or Na, K and Rb supported on bulk Co. A particularly preferred supported catalyst composition for LTS and MTS activity is sodium hydroxide promoted Ru—Co/ZrO₂ where sodium hydroxide is a precursor that provides the source of Na.

B. Catalyst Components a) and b): Ru and Co

Ru, its oxides or mixtures thereof and Co, its oxides or mixtures thereof are required metal components in a catalyst composition of the invention. Ru and Co may be present in an independent combination of their reduced forms and their oxides.

Unmodified Ru has been shown to catalyze the WGS reaction and is more active and less selective than Pt. Co is an example of a performance additive for Ru, along with the other components of the invention. Co may be present in the WGS catalyst compositions of the invention in a bulk state.

C. Catalyst Component c): Components other than Ru and Co

The platinum-free WGS catalysts of the invention contain at least three metals or metalloids. In addition to the Ru and Co components discussed above, the catalyst contains metals or metalloids which, when used in combination with Ru and Co, function to impart beneficial properties to the catalyst of the invention. A catalyst of the invention, then, further comprises at least one of Li, Na, K, Rb, Cs, Ti, Zr, Cr, Mo, Fe, La, Ce, Eu, their oxides and mixtures thereof.

D. Functional Classification of Catalyst Components

Without limiting the scope of the invention, discussion of the functions of the various catalyst components is offered, along with a template for composing catalyst compositions according to the invention. The following classification of catalyst components will direct one of skill in the art in the selection of various catalyst components to formulate WGS catalyst compositions according to the present invention and depending on the reaction conditions of interest.

Furthermore, there are several metals which may be incorporated into a water gas shift catalyst according to the invention. Hence, the various elements recited as components in any of the described embodiments may be included in any various combination and permutation to achieve a catalyst composition that is coarsely or finely tuned for a specific application (e.g., including for a specific set of conditions, such as, temperature, pressure, space velocity, catalyst precursor, catalyst loading, catalyst surface area/presentation, reactant flow rates, reactant ratios, etc.). In some cases, the effect of a given component may vary with the operating temperature for the catalyst. These catalyst components may function as, for instance, activators or moderators depending upon their effect on the performance characteristics of the catalyst. For example, if greater activity is desired, an activator may be incorporated into a catalyst, or a moderator may be replaced by at least one activator or, alternatively, by at least one moderator one step further up the “activity ladder.” An “activity ladder” ranks secondary or added catalyst components, such as activators or moderators, in order of the magnitude of their respective effect on the performance of a principal catalyst constituent. Conversely, if WGS selectivity of a catalyst needs to be increased (e.g. decrease the occurrence of the competing methanation reaction), then either an activator may be removed from the catalyst or, alternatively, the current moderator may be replaced by at least one moderator one step down the “activity ladder.” The function of these catalyst components may be further described as “hard” or “soft” depending on the relative effect obtained by incorporating a given component into a catalyst. The catalyst components may be metals, metalloids, or non-metals.

As an example, the undoped combination of Ru and Co results in an active but unselective WGS catalyst at higher temperatures. Doping with a moderator of at least one of Na, K and Rb dramatically enhances selectivity of the catalyst such that the LTS and MTS selectivity approaches or surpasses Pt/ZrO₂, especially at higher temperatures. Of the doping metals, Na is the most active and efficient at LTS but K and Rb are the most selective at MTS. Additional Zr doping is expected to further enhance performance.

An example of another embodiment of a WGS catalyst of the invention is Ru—Co—Fe. The Ru—Co—Fe catalyst exhibits synergistic properties and can be used as a bulk catalyst (e.g., precipitated CoFe optionally doped with other metals) or supported on conventional carriers such as zirconia, titania or ceria. At LTS and MTS, Fe acts an efficient selectivity-enhancing moderator to the otherwise too active and unselective Ru and Co combination. At higher temperatures, however, Fe becomes active on its own and therefore adds to overall activity of the Ru—Co—Fe ternary. High surface areas can be achieved by supporting the Ru—Co—Fe catalyst on conventional carriers such as, for example, zirconia and/or by adding stabilizing components such as, for example, Cr, La and Ce.

According to the present invention Ru and Co are active and selective WGS-promoting metals. The Ru—Co combination may be activated by activators which include, but are not limited to, Li, Na, K, Rb, Ti, Zr and Ce. Ce may be the most active rare earth metal for activating the WGS reaction. La and Eu may also be active, particularly at lower temperatures. In general, all lanthanides, other than Ce, show comparable performance and tend to moderate rather than activate noble metal containing catalyst systems. La is only slightly moderating when doping Ce and may therefore be used to adjust the selectivity of Ce containing catalyst systems. Fe is an example of a selective activator over a broad dynamic range.

E. Supports

The support or carrier may be any support or carrier used with the catalyst which allows the water gas shift reaction to proceed. The support or carrier may be a porous, adsorptive, high surface area support with a surface area of about 25 to about 500 m²/g. The porous carrier material may be relatively inert to the conditions utilized in the WGS process, and may include carrier materials that have traditionally be utilized in hydrocarbon steam reforming processes, such as, (1) activated carbon, coke, or charcoal; (2) silica or silica gel, silicon carbide, clays, and silicates including those synthetically prepared and naturally occurring, for example, china clay, diatomaceous earth, fuller's earth, kaolin, etc.; (3) ceramics, porcelain, bauxite; (4) refractory inorganic oxides such as alumina, titanium dioxide, zirconium oxide, magnesia, etc.; (5) crystalline and amorphous aluminosilicates such as naturally occurring or synthetically prepared mordenite and/or faujasite; and, (6) combinations of these groups.

When a WGS catalyst of the invention is a supported catalyst, the support utilized may contain one or more of the metals (or metalloids) of the catalyst. The support may contain sufficient or excess amounts of the metal for the catalyst such that the catalyst may be formed by combining the other components with the support. Examples of such supports include ceria which can contribute cerium, Ce, to a catalyst or iron oxide which can contribute iron, Fe. When such supports are used, the amount of the catalyst component in the support typically may be far in excess of the amount of the catalyst component needed for the catalyst. Thus the support may act as both an active catalyst component and a support material for the catalyst. Alternatively, the support may have only minor amounts of a metal making up the WGS catalyst such that the catalyst may be formed by combining all desired components on the support.

Carrier screening with Pt as the only active noble metal revealed that a water gas shift catalyst may also be supported on a carrier comprising alumina, zirconia, titania, ceria, magnesia, lanthania, niobia, zeolite, perovskite, silica clay, yttria and iron oxide. Perovskite as well as supported perovskites (e.g., supported on any of the previously listed carriers) may also be utilized as a support for the inventive catalyst formulations.

Zirconia, titania and ceria may be supports for the present invention and provide high activity for the WGS reaction. Niobia, yttria and iron oxide carriers provide high selectivity but are also less active which is believed to be due to a lack of surface area. In addition to their use as carriers, iron, yttrium and magnesium oxides may be utilized as primary layers on zirconia carriers to provide both higher surface area and low moderator concentration.

In general, alumina has been found to be an active but unselective carrier for Pt only containing WGS catalysts. However, the selectivity of gamma alumina may be improved by doping with Zr, Co, or one of the rare earth elements, such as, for example, La and Ce alone or in combination. This doping may be accomplished by addition of the oxides or other salts such as nitrates, in either liquid or solid form, to the alumina. Other possible dopants to increase the selectivity include redox dopants, such as for instance, Re, Mo, Fe, and basic dopants. Preferred is an embodiment of gamma alumina combined with Zr and/or Co which exhibits both high activity and selectivity over a broad temperature range.

High surface area aluminas, such as gamma-, delta- or theta-alumina are preferred alumina carriers. Other alumina carriers, such as mixed silica alumina, sol-gel alumina, and sol-gel or coprecipitated alumina-zirconia carriers may be used. Alumina typically has a higher surface area and a higher pore volume than carriers such as zirconia and usually offers a price advantage over other more expensive carriers.

Zirconia is a preferred carrier for use with the WGS catalysts of the invention. Monoclinic zirconia is particularly preferred. When zirconia, particularly monoclinic zirconia, is used as the catalyst carrier, the resulting catalyst compositions have shown enhanced activity under LTS conditions. That is in contrast with other carriers such as gamma alumina. This carrier effect is less pronounced for catalysts containing Na in view of Na tending to cover the surface of the carrier.

Examples of a carrier supported platinum-free WGS catalyst of the invention include: Ru—Co—{Zr, Eu, Mo, Fe, Na}/γ-Al₂O₃, particularly Ru—Co—Zr/γ-Al₂O₃; Ru—Co—Eu/γ-Al₂O₃; Ru—Co—Mo/γ-Al₂O₃; Ru—Co—Fe/γ-Al₂O₃; and Ru—Co—Na/γ-Al₂O₃; and

F. Methods of Making a WGS Catalyst

As set forth above, a platinum-free WGS catalyst of the invention may be prepared by mixing the metals and/or metalloids in their elemental forms or as oxides or salts to form a catalyst precursor, which generally undergoes a calcination and/or reductive treatment. Without being bound by theory, the catalytically active species are generally understood to be species which are in the reduced elemental state or in other possible higher oxidation states.

The WGS catalysts of the invention may be prepared by any well known catalyst synthesis processes. See, for example, U.S. Pat. Nos. 6,299,995 and 6,293,979. Spray drying, precipitation, impregnation, incipient wetness, ion exchange, fluid bed coating, physical or chemical vapor deposition are just examples of several methods that may be utilized to make the present WGS catalysts. Preferred approaches, include, for instance, impregnation or incipient wetness. The catalyst may be in any suitable form, such as, pellets, granular, bed, or monolith. See also the co-pending U.S. patent application Ser. No. 10/739,428 listing Hagemeyer et al., and filed on the same date as the present application under for further details on methods of atalyst preparation and catalyst precursors.

The WGS catalyst of the invention may be prepared on a solid support or carrier material. Preferably, the support or carrier is, or is coated with, a high surface area material onto which the precursors of the catalyst are added by any of several different possible techniques, as set forth above and as known in the art. The catalyst of the invention may be employed in the form of pellets, or on a support, preferably a monolith, for instance a honeycomb monolith.

Catalyst precursor solutions are preferably composed of easily decomposable forms of the catalyst component in a sufficiently high enough concentration to permit convenient preparation. Examples of easily decomposable precursor forms include the nitrate, amine, and oxalate salts. Typically chlorine containing precursors are avoided to prevent chlorine poisoning of the catalyst. Solutions can be aqueous or non-aqueous solutions. Exemplary non-aqueous solvents can include polar solvents, aprotic solvents, alcohols, and crown ethers, for example, tetrahydrofuran and ethanol. Concentration of the precursor solutions generally may be up to the solubility limitations of the preparation technique with consideration given to such parameters as, for example, porosity of the support, number of impregnation steps, pH of the precursor solutions, and so forth. The appropriate catalyst component precursor concentration can be readily determined by one of ordinary skill in the art of catalyst preparation.

Preferably, titanium dioxide in the anatase form is utilized as a catalyst precursor material.

V—Vanadium (IV) oxalate, a vanadium precursor, may be prepared from V₂O₅, (Aldrich), which is slurried in 1.5M aqueous oxalic acid on hot plate, for 1 hour until it turns dark blue due to V(V) reduction to V(IV) by oxalic acid. Ammonium metavanadate(V), (NH₄)VO₃, (Cerac, Alfa) may be used as a precursor by dissolving it in water, preferably hot, about 80° C. water. Various polycarboxylic organic acid vanadium precursors can be prepared and used as catalyst precursors, for example, citric, maleic, malonic, and tatartic. Vanadium citrate can be prepared by reacting V₂O₅ with citric acid, and heating to about 80° C. Ammonium vanadium(V) oxalate may be prepared by reacting (NH₄)VO₃ and NH₄OH in room temperature water, increasing temperature to 90° C., stirring to dissolve all solids, cooling to room temperature and adding oxalic acid; this produces a clear orange solution, which is stable for about 2 days.

3. Producing a Hydrogen-rich Gas, such as, a Hydrogen-rich Syngas

The invention also relates to a method for producing a hydrogen-rich gas, such as, a hydrogen-rich syngas. An additional embodiment of the invention may be directed to a method of producing a CO-depleted gas, such as a CO-depleted syngas.

A CO-containing gas, such as a syngas, contacts with a water gas shift catalyst in the presence of water according to the method of the invention. The reaction preferably may occur at a temperature of less than 450° C. to produce a hydrogen-rich gas, such as a hydrogen-rich syngas.

A method of the invention may be utilized over a broad range of reaction conditions. Preferably, the method is conducted at a pressure of no more than about 75 bar, preferably at a pressure of no more than about 50 bar to produce a hydrogen-rich syngas. Even more preferred is to have the reaction occur at a pressure of no more than about 25 bar, or even no more than about 15 bar, or not more than about 10 bar. Especially preferred is to have the reaction occur at, or about atmospheric pressure. Depending on the formulation of the catalyst according to the present invention, the present method may be conducted at reactant gas temperatures ranging from less than about 250° C. to up to about 450° C. Preferably, the reaction occurs at a temperature selected from one or more temperature subranges of LTS, MTS and/or HTS as described above. Space velocities may range from about 1 hr⁻¹ up to about 1,000,000 hr⁻¹. Feed ratios, temperature, pressure and the desired product ratio are factors that would normally be considered by one of skill in the art to determine a desired optimum space velocity for a particular catalyst formulation.

4. Fuel Processor Apparatus

The invention further relates to a fuel processing system for generation of a hydrogen-rich gas from a hydrocarbon or substituted hydrocarbon fuel. Such a fuel processing system would comprise, for example, a fuel reformer, a water gas shift reactor and a temperature controller.

The fuel reformer would convert a fuel reactant stream comprising a hydrocarbon or a substituted hydrocarbon fuel to a reformed product stream comprising carbon monoxide and water. The fuel reformer may typically have an inlet for receiving the reactant stream, a reaction chamber for converting the reactant stream to the product stream, and an outlet for discharging the product stream.

The fuel processor system would also comprise a water gas shift reactor for effecting a water gas shift reaction at a temperature of less than about 450° C. This water gas shift reactor may comprise an inlet for receiving a water gas shift feed stream comprising carbon monoxide and water from the product stream of the fuel reformer, a reaction chamber having a water gas shift catalyst as described herein located therein, and an outlet for discharging the resulting hydrogen-rich gas. The water gas shift catalyst would preferable be effective for generating hydrogen and carbon dioxide from the water gas shift feed stream.

The temperature controller may be adapted to maintain the temperature of the reaction chamber of the water gas shift reactor at a temperature of less than about 450° C.

5. INDUSTRIAL APPLICATIONS

Syngas is used as a reactant feed in number of industrial applications, including for example, methanol synthesis, ammonia synthesis, oxoaldehyde synthesis from olefins (typically in combination with a subsequent hydrogenation to form the corresponding oxoalcohol), hydrogenations and carbonylations. Each of these various industrial applications preferably includes a certain ratio of H₂ to CO in the syngas reactant stream. For methanol synthesis the ratio of H₂:CO is preferably about 2:1. For oxosynthesis of oxoaldehydes from olefins, the ratio of H₂:CO is preferably about 1:1. For ammonia synthesis, the ratio of H₂ to N₂ (e.g., supplied from air) is preferably about 3:1. For hydrogenations, syngas feed streams that have higher ratios of H₂:CO are preferred (e.g., feed streams that are H₂ enriched, and that are preferably substantially H₂ pure feed streams). Carbonylation reactions are preferably effected using feed streams that have lower ratios of H₂:CO (e.g., feed streams that are CO enriched, and that are preferably substantially CO pure feed streams).

The WGS catalysts of the present invention, and the methods disclosed herein that employ such WGS catalysts, can be applied industrially to adjust or control the relative ratio H₂:CO in a feed stream for a synthesis reaction, such as methanol synthesis, ammonia synthesis, oxoaldehyde synthesis, hydrogenation reactions and carbonylation reactions. In one embodiment, for example, a syngas product stream comprising CO and H₂ can be produced from a hydrocarbon by a reforming reaction in a reformer (e.g., by steam reforming of a hydrocarbon such as methanol or naphtha). The syngas product stream can then be fed (directly or indirectly after further downstream processing) as the feed stream to a WGS reactor, preferably having a temperature controller adapted to maintain the temperature of the WGS reactor at a temperature of about 450° C. or less during the WGS reaction (or at lower temperatures or temperature ranges as described herein in connection with the catalysts of the present invention). The WGS catalyst(s) employed in the WGS reactor are preferably selected from one or more of the catalysts and/or methods of the invention. The feed stream to the WGS reactor is contacted with the WGS catalyst(s) under reaction conditions effective for controlling the ratio of H₂:CO in the product stream from the WGS reactor (i.e., the “shifted product stream”) to the desired ratio for the downstream reaction of interest (e.g, methanol synthesis), including to ratios described above in connection with the various reactions of industrial significance. As a non-limiting example, a syngas product stream from a methane steam reformer will typically have a H₂:CO ratio of about 6:1. The WGS catalyst(s) of the present invention can be employed in a WGS reaction (in the forward direction as shown above) to further enhance the amount of H₂ relative to CO, for example to more than about 10:1, for a downstream bydrogenation reaction. As another example, the ratio of H₂:CO in such a syngas product stream can be reduced by using a WGS catalyst(s) of the present invention in a WGS reaction (in the reverse direction as shown above) to achieve or approach the desired 2:1 ratio for methanol synthesis. Other examples will be known to a person of skill in the art in view of the teachings of the present invention.

A person of skill in the art will understand and appreciate that with respect to each of the preferred catalyst embodiments as described in the preceding paragraphs, the particular components of each embodiment can be present in their elemental state, or in one or more oxide states, or mixtures thereof.

Although the foregoing description is directed to the preferred embodiments of the invention, it is noted that other variations and modifications will be apparent to those skilled in the art, and which may be made without departing from the spirit or scope of the invention.

EXAMPLES

General

Small quantity catalyst composition samples are generally prepared by automated liquid dispensing robots (Cavro Scientific Instruments) on flat quartz test wafers.

Generally, supported catalysts are prepared by providing a catalyst support (e.g. alumina, silica, titania, etc.) to the wafer substrate, typically as a slurry composition using a liquid-handling robot to individual regions or locations on the substrate or by wash-coating a surface of the substrate using techniques known to those of skill in the art, and drying to form dried solid support material on the substrate. Discrete regions of the support-containing substrate are then impregnated with specified compositions intended to operate as catalysts or catalyst precursors, with the compositions comprising metals (e.g. various combinations of transition metal salts). In some circumstances the compositions are delivered to the region as a mixture of different metal-containing components and in some circumstances (additionally or alternatively) repeated or repetitive impregnation steps are performed using different metal-containing precursors. The compositions are dried to form supported catalyst precursors. The supported catalyst precursors are treated by calcining and/or reducing to form active supported catalytic materials at discrete regions on the wafer substrate.

Bulk catalysts (e.g. noble-metal-free Co-containing catalysts) may also be prepared on the substrate. Such multi-component bulk catalysts are purchased from a commercial source and/or are prepared by precipitation or co-precipitation protocols, and then optionally treated—including mechanical pretreatment (grinding, sieving, pressing). The bulk catalysts are placed on the substrate, typically by slurry dispensing and drying, and then optionally further doped with additional metal-containing components (e.g. metal salt precursors) by impregnation and/or incipient wetness techniques to form bulk catalyst precursors, with such techniques being generally known to those of skill in the art. The bulk catalyst precursors are treated by calcining and/or reducing to form active bulk catalytic materials at discrete regions on the wafer substrate.

The catalytic materials (e.g., supported or bulk) on the substrate are tested for activity and selectivity for the WGS reaction using a scanning mass spectrometer (“SMS”) comprising a scanning/sniffing probe and a mass spectrometer. More details on the scanning mass spectrometer instrument and screening procedure are set forth in U.S. Pat. No. 6,248,540, in European Patent No. EP 101994 and in European Patent Application No. EP 1186892 and corresponding U.S. application Ser. No. 09/652,489 filed Aug. 31, 2000 by Wang et al., the complete disclosure of each of which is incorporated herein in its entirety. Generally, the reaction conditions (e.g. contact time and/or space velocities, temperature, pressure, etc.) associated with the scanning mass spectrometer catalyst screening reactor are controlled such that partial conversions (i.e., non-equilibrium conversions, e.g., ranging from about 10% to about 40% conversion) are obtained in the scanning mass spectrometer, for discrimination and ranking of catalyst activities for the various catalytic materials being screened. Additionally, the reaction conditions and catalyst loadings are established such that the results scale appropriately with the reaction conditions and catalyst loadings of larger scale laboratory research reactors for WGS reactions. A limited set of tie-point experiments are performed to demonstrate the scalability of results determined using the scanning mass spectrometer to those using larger scale laboratory research reactors for WGS reactions. See, for example, Example 12 of U.S. patent application Ser. No. 60/434,708 entitled “Platinum-Ruthenium Containing Catalyst Formulations for Hydrogen Generation,” filed by Hagemeyer et al. on Dec. 20, 2002.

Preparative and Testing Procedures

The catalysts and compositions of the present invention were identified using high-throughput experimental technology, with the catalysts being prepared and tested in library format, as described generally above, and in more detail below. Specifically, such techniques were used for identifying catalyst compositions that were active and selective as WGS catalysts. As used in these examples, a “catalyst library” refers to an associated collection of candidate WGS catalysts arrayed on a wafer substrate, and having at least two, and typically three or more common metal components (including metals in the fully reduced state, or in a partially or fully oxidized state, such as metal salts), but differing from each other with respect to relative stoichiometry of the common metal components.

Depending on the library design and the scope of the investigation with respect to a particular library, multiple (i.e., two or more) libraries were typically formed on each wafer substrate. A first group of test wafers each comprised about 100 different catalyst compositions formed on a three-inch wafer substrate, typically with most catalysts being formed using at least three different metals. A second group of test wafers each comprised about 225 different catalyst compositions on a four-inch wafer substrate, again typically with most catalysts being formed using at least three different metals. Each test wafer itself typically comprised multiple libraries. Each library typically comprised binary, ternary or higher-order compositions—that is, for example, as ternary compositions that comprised at least three components (e.g., A, B, C) combined in various relative ratios to form catalytic materials having a molar stoichiometry covering a range of interest (e.g., typically ranging from about 20% to about 80% or more (e.g. to about 100% in some cases) of each component). For supported catalysts, in addition to varying component stoichiometry for the ternary compositions, relative total metal loadings were also investigated.

Typical libraries formed on the first group of (three-inch) test wafers included, for example, “five-point libraries” (e.g., twenty libraries, each having five different associated catalyst compositions), or “ten-point” libraries (e.g., ten libraries, each having ten different associated catalyst compositions), or “fifteen-point libraries” (e.g., six libraries, each having fifteen different associated catalyst compositions) or “twenty-point libraries” (e.g., five libraries, each having twenty different associated catalyst compositions). Typical libraries formed on the second group of (four-inch) test wafers included, for example, “nine-point libraries” (e.g., twenty-five libraries, each having nine different associated catalyst compositions), or “twenty-five point” libraries (e.g., nine libraries, each having twenty-five different associated catalyst compositions). Larger compositional investigations, including “fifty-point libraries” (e.g., two or more libraries on a test wafer, each having fifty associated catalyst compositions), were also investigated. Typically, the stoichiometric increments of candidate catalyst library members ranged from about 1.5% (e.g for a “fifty-five point ternary”) to about 15% (e.g., for a “five-point” ternary). See, generally, for example, WO 00/17413 for a more detailed discussion of library design and array organization. FIGS. 9A to 9F of the instant application show library designs for libraries prepared on a common test wafer, as graphically represented using Library Studios® (Symyx Technologies, Inc., Santa Clara, Calif.), where the libraries vary with respect to both stoichiometry and catalyst loading. Libraries of catalytic materials that vary with respect to relative stoichiometry and/or relative catalyst loading can also be represented in a compositional table, such as is shown in the several examples of this application.

Referring to FIG. 9A, for example, the test wafer includes nine libraries, where each of the nine libraries comprise nine different ternary compositions of the same three-component system. In the nomenclature of the following examples, such a test wafer is said to include nine, nine-point-ternary (“9PT”) libraries. The library depicted in the upper right hand corner of this test wafer includes catalyst compositions comprising components A, B and X₁ in 9 different stoichiometries. As another example, with reference to FIG. 9B, a partial test wafer is depicted that includes a fifteen-point-ternary (“15PT”) library having catalyst compositions of Pt, Pd and Cu in fifteen various stoichiometries. Generally, the composition of each catalyst included within a library is graphically represented by an association between the relative amount (e.g., moles or weight) of individual components of the composition and the relative area shown as corresponding to that component. Hence, referring again to the fifteen different catalyst compositions depicted on the partial test wafer represented in FIG. 9B, it can be seen that each composition includes Pt (red), Pd (green) and Cu (blue), with the relative amount of Pt increasing from column 1 to column 5 (but being the same as compared between rows within a given column), with the relative amount of Pd decreasing from row 1 to row 5 (but being the same as compared between columns within a given row), and with the relative amount of Cu decreasing from a maximum value at row 5, column 1 to a minimum at, for example, row 1, column 1. FIG. 9C shows a test wafer that includes a fifty-point-ternary (“50PT”) library having catalyst compositions of Pt, Pd and Cu in fifty various stoichiometries. This test library could also include another fifty-point ternary library (not shown), for example with three different components of interest.

FIGS. 9D through 9F are graphical representations of two fifty-point ternary libraries (“bis 50PT libraries”) at various stages of preparation—including a Pt—Au—Ag/CeO₂ library (shown as the upper right ternary library of FIG. 9E) and a Pt—Au—Ce/ZrO₂ library (shown as the lower left ternary library of FIG. 9E). Note that the Pt—Au—Ag/CeO₂ library also includes binary-impregnated compositions—Pt—Au/CeO₂ binary catalysts (row 2) and Pt—Ag/CeO₂ (column 10). Likewise, the Pt—Au—Ce/ZrO₂ library includes binary-impregnated compositions—Pt—Ce/ZrO₂ (row 11) and Au—Ce/ZrO₂ (column 1). Briefly, the bis 50PT libraries were prepared by depositing CeO₂ and ZrO₂ supports onto respective portions of the test wafer as represented graphically in FIG. 9D. The supports were deposited onto the test wafer as a slurry in a liquid media using a liquid handling robot, and the test wafer was subsequently dried to form dried supports. Thereafter, salts of Pt, Au and Ag were impregnated onto the regions of the test wafer containing the CeO₂ supports in the various relative stoichiometries as represented in FIG. 9E (upper-right-hand library). Likewise, salts of Pt, Au and Ce were impregnated onto the regions of the test wafer containing the ZrO₂ supports in the various relative stoichiometries as represented in FIG. 9E (lower-left-hand library). FIG. 9F is a graphical representation of the composite library design, including the relative amount of catalyst support.

Specific compositions of tested catalytic materials of the invention are detailed in the following examples for selected libraries.

Performance benchmarks and reference experiments (e.g., blanks) were also provided on each quartz catalyst test wafer as a basis for comparing the catalyst compositions of the libraries on the test wafer. The benchmark catalytic material formulations included a Pt/zirconia catalyst standard with about 3% Pt catalyst loading (by weight, relative to total weight of catalyst and support). The Pt/zirconia standard was typically synthesized by impregnating 3 μL of, for example, 1.0% or 2.5% by weight Pt stock solution onto zirconia supports on the wafer prior to calcination and reduction pretreatment.

Typically wafers were calcined in air at a temperature ranging from 300° C. to 500° C. and/or reduced under a continuous flow of 5% hydrogen at a temperature ranging from about 200° C. to about 500° C. (e.g., 450° C.). Specific treatment protocols are described below with respect to each of the libraries of the examples.

For testing using the scanning mass spectrometer, the catalyst wafers were mounted on a wafer holder which provided movement in an XY plane. The sniffing/scanning probe of the scanning mass spectrometer moved in the Z direction (a direction normal to the XY plane of movement for the wafer holder), and approached in close proximity to the wafer to surround each independent catalyst element, deliver the feed gas and transmit the product gas stream from the catalyst surface to the quadrupole mass spectrometer. Each element was heated locally from the backside using a CO₂laser, allowing for an accessible temperature range of about 200° C. to about 600° C. The mass spectrometer monitored seven masses for hydrogen, methane, water, carbon monoxide, argon, carbon dioxide and krypton: 2, 16, 18, 28, 40, 44 and 84, respectively.

Catalyst compositions were tested at various reaction temperatures, typically including for example at about 300° C., 350° C. and/or 400° C. and, additionally, usually for more active formulations, at 250° C. Particularly for LTS formulations, testing of catalytic activity at reaction temperatures starting as low as 200° C. may occur. The feed gas typically consisted of 51.6% H₂, 7.4% Kr, 7.4% CO, 7.4% CO₂ and 26.2% H₂O. The H₂, CO, CO₂ and Kr internal standards are premixed in a single gas cylinder and then combined with the water feed. Treated water (18.1 mega-ohms-cm at 27.5° C.) produced by a Barnstead Nano Pure Ultra Water system was used, without degassing.

Data Processing and Analysis

Data analysis was based on mass balance plots where CO conversion was plotted versus CO₂ production. The mass spectrometer signals were uncalibrated for CO and CO₂ but were based on Kr-normalized mass spectrometer signals. The software package Spotfire™ (sold by Spotfire, Inc. of Somerville, Mass.) was used for data visualization.

A representative plot of CO conversion versus CO₂ production for a WGS reaction is shown in FIG. 10A involving, for discussion purposes, two ternary catalyst systems—a Pt—Au—Ag/CeO₂ catalyst library and a Pt—Au—Ce/ZrO₂ catalyst library—as described above in connection with FIGS. 9D through 9F. The catalyst compositions of these libraries were screened at four temperatures: 250° C., 300° C., 350° C. and 400° C. With reference to the schematic diagram shown in FIG. 10B, active and highly selective WGS catalysts (e.g., Line I of FIG. 10B) will approach a line defined by the mass balance for the water-gas-shift reaction (the “WGS diagonal”) with minimal deviation, even at relatively high conversions (i.e., at CO conversions approaching the thermodynamic equilibrium conversion (point “TE” on FIG. 10B)). Highly active catalysts may begin to deviate from the WGS diagonal due to cross-over to the competing methanation reaction (point “M” on FIG. 10C). Catalyst compositions that exhibit such deviation may still, however, be useful WGS catalysts depending on the conversion level at which such deviation occurs. For example, catalysts that first deviate from the WGS diagonal at higher conversion levels (e.g., Line II of FIG. 10B) can be employed as effective WGS catalysts by reducing the overall conversion (e.g., by lowering catalyst loading or by increasing space velocity) to the operational point near the WGS diagonal. In contrast, catalysts that deviate from the WGS diagonal at low conversion levels (e.g., Line III of FIG. 10B) will be relatively less effective as WGS catalysts, since they are unselective for the WGS reaction even at low conversions. Temperature affects the thermodynamic maximum CO conversion, and can affect the point of deviation from the mass-balance WGS diagonal as well as the overall shape of the deviating trajectory, since lower temperatures will generally reduce catalytic activity. For some compositions, lower temperatures will result in a more selective catalyst, demonstrated by a WGS trajectory that more closely approximates the WGS mass-balance diagonal. (See FIG. 10C). Referring again to FIG. 10A, it can be seen that the Pt—Au—Ag/CeO₂ and the Pt—Au—Ce/ZrO₂ catalyst compositions are active and selective WGS catalysts at each of the screened temperatures, and particularly at lower temperatures.

Generally, the compositions on a given wafer substrate were tested together in a common experimental run using the scanning mass spectrometer and the results were considered together. In this application, candidate catalyst compositions of a particular library on the substrate (e.g., ternary or higher-order catalysts comprising three or more metal components) were considered as promising candidates for an active and selective commercial catalyst for the WGS reaction based on a comparison to the Pt/ZrO₂ standard composition included on that wafer. Specifically, libraries of catalytic materials were deemed to be particularly preferred WGS catalysts if the results demonstrated that a meaningful number of catalyst compositions in that library compared favorably to the Pt/ZrO₂ standard composition included on the wafer substrate with respect to catalytic performance. In this context, a meaningful number of compositions was generally considered to be at least three of the tested compositions of a given library. Also in this context, favorable comparison means that the compositions had catalytic performance that was as good as or better than the standard on that wafer, considering factors such as conversion, selectivity and catalyst loading. All catalyst compositions of a given library were in many cases positively identified as active and selective WGS catalysts even in situations where only some of the library members compared favorably to the Pt/ZrO₂ standard, and other compositions within that library compared less than favorably to the Pt/ZrO₂ standard. In such situations, the basis for also including members of the library that compared somewhat less favorably to the standard is that these members in fact positively catalyzed the WGS reaction (i.e. were effective as catalysts for this reaction). Additionally, it is noted that such compositions may be synthesized and/or tested under more optimally tuned conditions (e.g., synthesis conditions, treatment conditions and/or testing conditions (e.g., temperature)) than occurred during actual testing in the library format, and significantly, that the optimal conditions for the particular catalytic materials being tested may differ from the optimal conditions for the Pt/ZrO₂ standard—such that the actual test conditions may have been closer to the optimal conditions for the standard than for some of the particular members. Therefore, it was specifically contemplated that optimization of synthesis, treatment and/or screening conditions, within the generally defined ranges of the invention as set forth herein, would result in even more active and selective WGS catalysts than what was demonstrated in the experiments supporting this invention. Hence, in view of the foregoing discussion, the entire range of compositions defined by each of the claimed compositions (e.g., each three-component catalytic material, or each four-component catalytic material) was demonstrated as being effective for catalyzing the WGS reaction. Further optimization is considered, with various specific advantages associated with various specific catalyst compositions, depending on the desired or required commercial application of interest. Such optimization can be achieved, for example, using techniques and instruments such as those described in U.S. Pat. No. 6,149,882 or those described in WO 01/66245 and its corresponding U.S. applications, U.S. Ser. No. 09/801,390, entitled “Parallel Flow Process Optimization Reactor” filed Mar. 7, 2001 by Bergh et al., and U.S. Ser. No. 09/801,389, entitled “Parallel Flow Reactor Having Variable Feed Composition” filed Mar. 7, 2001 by Bergh et al., each of which are incorporated herein by reference for all purposes.

Additionally, based on the results of screening of initial libraries, selective additional “focus” libraries were selectively prepared and tested to confirm the results of the initial library screening, and to further identify better performing compositions, in some cases under the same and/or different conditions. The test wafers for the focus libraries typically comprised about 225 different candidate catalyst compositions formed on a four-inch wafer substrate, with one or more libraries (e.g. associated ternary compositions A, B, C) formed on each test wafer. Again, the metal-containing components of a given library were typically combined in various relative ratios to form catalysts having stoichiometry ranging from about 0% to about 100% of each component, and for example, having stoichiometric increments of about 10% or less, typically about 2% or less (e.g., for a “fifty-six point ternary”). Focus libraries are more generally discussed, for example, in WO 00/17413. Such focus libraries were evaluated according to the protocols described above for the initial libraries.

The raw residual gas analyzer (rga) signal values generated by the mass spectrometer for the individual gases are uncalibrated and therefore different gases may not be directly compared. Methane data (mass 16) was also collected as a control. The signals are typically standardized by using the raw rga signal for krypton (mass 84) to remove the effect of gas flow rate variations. Thus, for each library element, the standardized signal is determined as, for example, sH₂O=raw H₂O/raw Kr; sCO=raw CO/raw Kr; sCO₂=raw CO₂/raw Kr and so forth.

Blank or inlet concentrations are determined from the average of the standardized signals for all blank library elements (i.e. library elements for which the composition contains at most only support). For example, b_(avg) H₂O=average sH₂O for all blank elements in the library; b_(avg) CO=average sCO for all blank elements in the library; and so forth.

Conversion percentages are calculated using the blank averages to estimate the input level (e.g., b_(avg) CO) and the standardized signal (e.g., sCO) as the output for each library element of interest. Thus, for each library element, CO_(conversion)=100×(b_(avg) CO−sCO)/b_(avg) CO and H2O_(conversion)=100×(b_(avg) H₂O—sH₂O)/b_(avg) H₂O.

The carbon monoxide (CO) to carbon dioxide (CO₂) selectivity is estimated by dividing the amount of CO₂ produced (sCO₂−b_(avg) CO₂) by the amount of CO consumed (b_(avg) CO−sCO). The C0₂ and CO signals are not directly comparable because the rga signals are uncalibrated. However, an empirical conversion constant (0.6 CO₂ units=1 CO unit) has been derived, based on the behavior of highly selective standard catalyst compositions. The selectivity of the highly selective standard catalyst compositions approach 100% selectivity at low conversion rates. Therefore, for each library element, estimated CO to CO₂ selectivity =100×0.6×(sCO₂−b_(avg) CO₂)/(b_(avg) CO−sCO). Low CO consumption rates can produce highly variable results, and thus the reproducibility of CO₂ selectivity is maintained by artificially limiting the CO₂ selectivity to a range of 0% to 140%.

The complete disclosure of the above mentioned application and all other references cited herein are incorporated herein in their entireties for all purposes.

The following examples are representative of the screening of libraries that lead to identification of the particularly claimed inventions herein.

Example 1

A 4″ quartz wafer was pre-coated with 14 columns of Engelhard Co-164 (bulk Co commercial catalyst) and ZrO₂ (Norton XZ16052) as reference carrier by slurry dispensing as a mnaster batch in volumes of 3μL (both 1.5 g/4 mL, EG/H₂O/MeO 32.5:30:37.5) to a 15×15 square on the wafer. After the dispensing step the wafer was oven-dried at 70° C. for 14 minutes.

Six internal standards were synthesized by Cavro spotting 3 μL of Pt(NH₃)₂(NO₂)₂ (stabilized, 2.5% Pt) stock solution into the corresponding first row/last column positions. The Co-bulk carrier pre-coated wafer was impregnated with a ruthenium(III) nitrosyl nitrate (diluted in dilute nitric acid and containing 1.5% Ru) gradient from top to bottom by Cavro dispensing from the respective stock solution vial to a microtiter plate and diluting with distilled water followed by a one-to-one transfer of the microtiter plate pattern to the wafer. The Ru solution was dispensed in 2.5 μL dispense volume per well resulting in a 14×15 point rectangle on the wafer (14 replicas of the 15 point Ru gradients).

Subsequently the ZrO₂ pre-coated carrier column no. 15 was impregnated with a 15 point single column Pt(NH₃)₂(NO₂)₂ (unstabilized, 1% Pt) gradient from bottom to top by Cavro dispensing from the corresponding stock Pt solution vial to a microtiter plate and diluting with distilled water followed by a one-to-one transfer to the wafer by dispensing 2.5 μL dispense volume per well.

The wafer was slowly dried overnight at room temperature. The Co-bulk carrier coated columns nos. 2–14 were coated with binary metal-gradients from bottom to top: C2: LiOH, C3: KOH, C4: NaOH, C5: RbOH (C2–C5: 1 molar), C6: Fe(NO₃)₃, C7: H₂MoO₄, C8: Ce(III)(NO₃)₃, C9: La(NO₃)₃ (C6–C9: 0.25 molar), C10: H₂IrCl₆ (1% Ir), C11: Cu(NO₃₎ ₂ (0.1 molar), C12: Mn(NO₃)₂ (0.25 molar), C13: Pd(NH₃)₂(NO₂)₂ (1% Pd), C14: Pt(NH₃)₂(NO₂)₂ (unstabilized, 1% Pt), by Cavro dispensing 2.5 μL per well from the respective stock solution vials as above resulting in a 13×15 point rectangle on the wafer. The wafer was slowly dried at room temperature for 3 hours and then reduced in a flow of 5% H₂/N₂ at 450° C. for 2 hours. Commercial catalyst was slurried into five positions of the first row and last column as external standard (3 μL catalyst slurry). See FIGS. 1A through 1C. The wafer was screened by SMS for WGS activity with a H₂/CO/CO₂/H₂O mixed feed at 200° C., 230° C. and 260° C.

This set of experiments demonstrated active and selective bulk cobalt supported WGS catalyst formulations.

Example 2

A 4″ quartz wafer was precoated with ZrO₂ carrier by repeated slurry dispensing of zirconia powder (Norton XZ16052/MEI FZO923/01 70:30 mix) onto the wafer (1 g zirconia powder in 4 mL EG/H₂O 50:50 mixture, 2 zirconia layers=2×3 μL=6 μL slurry dispensed in total). The zirconia carrier-precoated wafer was dried and then impregnated with gradients of the metals (Co, Ni, Cu, Fe and Ru). Advantageously, all metal precursor solutions (metal nitrates and Ru nitrosyl nitrate) are compatible and a single impregnation step suffices to deposit all the metals. The gradients were premixed in a microtiter plate by dilution of metal nitrate stock solutions with water. The diluted solutions are then transferred from the microtiter plate to the wafer by Cavro dispensing (3 μL dispense volume per well). The wafer was dried, calcined in air at 500° C. for 1 hour and then reduced in 5% H₂/Ar at 380° C. for 3 hours. See FIGS. 2A and 2B.

The reduced wafer was then screened by SMS for WGS activity with a H₂/CO/CO₂/H₂O mixed feed at 250° C., 300° C., 350° C. and 400° C.

This set of experiments demonstrated active and selective WGS catalyst formulations for Ru and Co containing formulations supported on zirconia.

Example 3

A 4″ quartz wafer was precoated with zirconia carrier by repeated slurry dispensing zirconia powder (Norton XZ16052) onto the wafer. The slurry was composed of 1.5 g zirconia powder in 4 mL of a MEO/EG/H₂O 40:30:30 mixture. A total of 3 μL of slurry was deposited on each spot.

The zirconia carrier precoated wafer was impregnated with separate concentration gradients of Co, Fe, Sm, Ge, Sn and Ti by Cavro dispensing from metal stock solution vials to a microtiter plate (five, four, one, two, one, two columns, respectively of each metal in 7-point (“7P”) and 8-point (“8P”) concentration gradients) followed by transferring replicas of the four 7P and 8P columns onto the wafer (2.5 μL dispense volume per well). The wafer was dried at 70° C. for 10 minutes.

The wafer was then impregnated with Fe, Zr, Ti, Mo, Eu, Sn, Sb and V concentration gradients by Cavro dispensing 2.5 μL per well in 7-point and 8-point gradients. The metal columns were arranged in the following order beginning on the left: Fe, Zr, Ti, Mo, Eu, Zr, Ti, Mo, Eu, Eu, Sn, Sb, Sb, V and Mo. For all of the above impregnations, Co, Fe, Sm and Eu were provided as their nitrates, Ge, Sn and V as their oxalates, Ti as the ammonium titanyl oxalate, Sb as the ammonium antimony oxalate, Zr as zirconyl nitrate and Mo as molybdic acid. The wafer was dried at 70° C. for 10 minutes.

The top seven rows of the wafer were uniformly coated with 2.5 μL per well of a RuNO(NO₃)₃ stock solution (0.5% Ru), and the bottom eight rows were uniformly coated with 2.5 μL per well of a Pt(NH₃)₂(NO₂)₂ stock solution (1% Pt). The wafer was calcined in air at 400° C. for 2 hours followed by reduction with 5% H₂/N₂ at 300° C. for 2 hours. Nine internal standards were synthesized by spotting 2.5 μL Pt(NH3)2(NO2)2 solution (2.5% Pt) into the corresponding first row/last column positions. See FIGS. 3A through 3G.

The reduced library was then screened in SMS for WGS activity with a H₂/CO/CO₂/H₂O mixed feed at 300° C. and 350° C. The CO conversion versus CO2 production results at 300° C. and 350° C. are presented in FIGS. 3H and 3I. More detailed test results, such as, CO conversion, CO₂ production and CH₄ production at 300° C. and 350° C. for each of the 225 individual catalyst wells on the test wafer are presented in Table 1.

This set of experiments demonstrated active and selective WGS catalyst formulations of various Ru—Co—{Fe, Zr, Ti, Mo, Eu,}/ZrO₂ formulations on the wafer.

Example 4

A 3″ quartz wafer was coated with niobia, ceria and magnesia carriers by slurry-dispensing aqueous carrier slurries onto the wafer (4 μL slurry/well, 1 g of carrier powder slurried in 2 mL H₂O for niobia and ceria; 500 mg of carrier powder slurried in 2 mL H₂O for magnesia). Niobia carriers were produced by Norton, product numbers 2001250214, 2000250356, 2000250355, 2000250354 and 2000250351. Cerias came from Norton (product 2001080053, 2001080052 and 2001080051) and Aldrich (product number 21,157-50. Magnesia was obtained from Aldrich (product number 24,338-8).

The carrier precoated wafer was then loaded with the same Pt gradient for each carrier in a single impregnation step by liquid dispensing 3 μL Pt(NH₃)₂(NO₂)₂ solution (5% Pt) from microtiter plate to wafer. The wafer was dried and then reduced in 5% H₂/Ar at 450° C. for 2 hours. See FIGS. 4A through 4C.

The reduced library was then screened in SMS for WGS activity with a H₂/CO/CO₂/H₂O mixed feed at 250° C., 300° C., 350° C., and 400° C. Results at 250° C., 300° C., 350° C., and 400° C. are presented in FIGS. 4D through 4H.

This set of experiments demonstrated active and selective WGS catalyst formulations of various Pt on one of Nb oxide, Ce oxide or Mg oxide formulations on the wafer. Various Norton niobia carriers were found to be very active and selective over a broad temperature range. Norton ceria 2001080051 was found to be very selective at higher temperatures. Magnesia was less active than either of niobia or ceria but did exhibit highly selective WGS performance.

This set of experiments demonstrated active and selective WGS catalyst formulations of various Pt on various of the oxide carrier formulations on the wafer.

Example 6

Scale-up catalyst samples were prepared by using incipient wetness impregnation of 0.75 grams of ZrO₂ support (Norton, 80–120 mesh) which had been weighed into a 10-dram vial. Aqueous metal precursor salt solutions were then added in the order: Ru, Fe, one of Co or Mo, then Na. The precursor salt solutions were ruthenium (III) nitrosylnitrate (1.5% Ru (w/v)), iron (III) nitrate (1.0M), cobalt (II) nitrate (1.0M), molybdic acid (1.0M), and sodium hydroxide (3.0N). All starting reagents were nominally research grade and purchased from Aldrich, Strem, or Alfa. Following each metal addition, the catalysts were dried at 80° C. overnight and then calcined in air as follows:

After Ru addition 450° C. for 3 hours After Fe addition 450° C. for 3 hours After Co or Mo addition 450° C. for 3 hours for Co, 350° C. for 3 hours for Mo.

Following Na addition, the catalysts were calcined at 300° C. for 3 hours, and then the catalysts were reduced in-situ at 300° C. for 3 hours in a 10% H₂/N₂ feed.

Catalyst Testing Conditions

Catalysts were tested in a fixed bed reactor. Approximately 0.15 g of catalyst was weighed and mixed with an equivalent mass of SiC. The mixture was loaded into a reactor and heated to reaction temperature. Reaction gases were delivered via mass flow controllers (Brooks) with water introduced with a metering pump (Quizix). The composition of the reaction mixture was as follows: H₂ 50%, CO 10%, CO₂ 10%, and H₂O 30%. The reactant mixture was passed through a pre-heater before contacting the catalyst bed. Following reaction, the product gases were analyzed using a micro gas chromatograph (Varian Instruments, or Shimadzu). Compositional data on the performance diagram (FIG. 6) is on a dry basis with water removed.
